Research and Data

2. Every population member has an equal chance of being selected. Strengthens external validity
3. Entire group of interest.
4. The outcome measured in a study.
5. Ordered categories with no equal spacing. Ex. Cancer staging for tumors grouped into four stages I through IV
8. Middle value when ordered.
11. Uses interviews, language, observations.
12. Uses numerical data.
14. Large marsupial
17. Statistics summarizing data without generalizing to populations
18. Rate of new cases over time.
20. Subset selected from a population
21. Most frequent value.
27. Similar to experiments but without randomization.
29. Variable manipulated by the researcher
30. Accuracy of study results or data
31. Consistency of measurements.
33. collected in a study.

1. observational study, they are analytic . Factors are measured at one specific moment in relation to the variable of interest.
6. States there is no difference between groups.
7. the degree to which the results of the study can be generalized beyond the specific group studied
9. Flying mammal
10. Proportion of existing cases of a disease/health condition in a population is measured at some designated time
13. measurement consist of named categories with no order
15. Arithmetic average.
16. Method to reduce bias . Typically is this kind of study the examiners are unaware of the group assignment and they are not aware which group is receiving the treatment or which is the control group
19. Using scientific evidence, patient preferences, and expertise
22. How well a study controls for bias or extraneous variables
23. A short summary stating the study’s purpose, methods, materials, and results
24. Study design where groups receive all treatments in different orders.
25. The best known and widely used Index measuring decayed, missing, and filled teeth.
26. Likes to chase mice
28. Has a trunk
32. Man's best friend
